The power button mounts to the power button bracket inside the HTC in the top right corner. This part will only replace a missing or damaged power button and does not typically control the functionality of the power button. Installation of this part will correct a cosmetically damaged but will not ensure a properly functioning Power button. If your Power button is not performing properly, you will need to order the HTC Sensation XL Replacement Flex Cable to correct that issue.
